Colmac Coil Manufacturing Inc.’s tested and patented technology allows for low charge industrial ammonia refrigeration designs using direct expansion (DX). The Low Temperature DX Ammonia system address the main issues associated with ammonia as a refrigerant, that have previously prevented its use at low suction temperatures. Colmac Coil’s newly published DX Ammonia Piping Handbook 2nd Edition provides engineers and designers with the guidelines needed for the successful design of low charge DX ammonia refrigeration systems from +10°C to -45.5°C (+50°F to -50°F).(Ammonia21)
